STEAM-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 710,654, dated October7, 1902.

Application filed April 2 1, 1901. Renewed February 3, 1902. Serial No,92,313. (No model.)

T 0 (tZZ whom/ it mmtg concern:

Be it known that I, JOHN ANGELL, a citizen of the United States ofAmerica, and a resident of St. Louis, in the State of Missouri, haveinvented certain new and useful 1mprovements in Steam-Separators, ofwhich the following is a specification.

The present invention relates to that type of separators for removingoil and water of condensation and entrainment from steam insteam-engineering plants.

The object of the present improvement is to provide a simple, compact,and efficient apparatus in which the separation is effected andmaintained in a very perfect manner and a remiXture by entrainmentprevented, all as will hereinafter more fully appear and be moreparticularly pointed out in the claims. I attain such object by theconstruction and arrangement of parts illustrated in the accompanyingdrawings, in which Figure 1 is a central longitudinal section at line 0000, Fig. 2, of a steam-separator embodying the present invention andillustrating an arrangement of the same for use on horizontally-arrangedsteam pipes or mains; Fig. 2, a View, partly in elevation and partly intransverse section, at line 00 Fig. 1; Fig. 3, a horizontal section ofthe same, taken on line 00 00 Fig. 1; Fig. 4, a central vertical sectionof a modified form of.the present invention at line 00 x Fig. 5; Fig. 5,a horizontal section through the upper or main portion of the same,taken at line x at", Fig. 4.

Similar numerals of reference indicate like parts in the several views.

Referring to the drawings, 1 represents the main separator-casing, ofany usual form and construction, but preferably of a substantiallyrectangular form, as shown, and having rounded upper corners to betterdeflect and direct the steam and an inclined bottom adapted toeffectively shed the oil and separated water down into thereceiving-chamber 2, which may be of any usual form and connected to themain separator-casing l indirectly by a reduced neck 3 in the main formof my present invention, as illustrated in Figs. 1, 2, and 3, or in adirect manner with-- out the intermediate neck, as illustrated in themodified form of the present invention illustrated in Figs. 1 and 5.

raters, in which a halide-plate is 4 and 5 are the respective inlet andoutlet necks or openings of the separator-casing, to which therespective portions 6 and 7 of the steam pipe or main are secured in anyusual manner, preferably by attaching-flanges 8 and 9, as shown, in viewof the fact that the same affords the more convenient means ofattachment to the large diameter of steam pipes or mains with which thepresent apparatus is most generally used, and in the present improvementfor the additional purpose of affording a convenient and substantialattachment for the detachable neck hereinafter described and which isintended to prevent a reentrainment at the outlet from the separator ofthe oil and water that has been previously separated in the apparatus.

10 is a detachable extension or neck provided atits outer end with anattaching-flange 11, by means of which it is secured in place betweenthe attaching-flange 9 of the steampipe and the side of the main casing,as shown. Such extension or neck is adapted to form a continuation ofthe steam-pipe section and is arranged toproject a distance into theinterior of the separator and at its inner end is provided with anangular marginal flange 12, that is adapted to prevent in a very perfectmanner the usual tendency of the oil and moisture upon the inner wall ofthe separator-casing to creep toward or in the direction of the outletfrom such casing.

13 is a vertical imperforate wall or partition arranged centrally withinthe separatorcasing and extending from side Wall to side wall of thecasing and from the bottom of said casing to within a short distancefrom the top of the same, so as to leave a passage or opening at suchpoint for the passage of the steam from the inlet to the outletorifices. It is material to the present construction that the upper endof such wall or partition extends some distance above the inlet andoutlet orifices, so that the course of the steam through the apparatuswill be a circuitous one and so that the incoming current of steam will.directly impact against the nearest face of such wall or partition, asusual to the present type of sepaarranged in the path of the steamthrough the separator.

The main feature of noveltyin the present invention involves thecombination,with such impact-wall located in the described manner, ofmeans for directing the incoming steam with its water, 850., ofentrainment in a di vided or disseminated condition against suchimpact-wall, so as to insure a very perfect separation of such oil,water, 850., the particles of which in the described disseminatedcondition as they impact against such wall readily lose their momentumand adhere thereto, to be subsequently carried by gravity down into thereceiving-chamber of the separator. Accordingly the above-mentioneddirecting and disseminating means will in the present invention comprisea construction as follows:

14 is a grid or break of a size substantially the same as the verticalimpact-wall 13 and arranged in adjacent vertical yet separated relationtherewith and preferably by means of a forwardly-curved flange 15 at theupper end of the impact-wall, as shown in Figs. 1 and 4. Such grid orbreak will preferably be formed by two vertically-arranged series ofbars 16, inclined downwardly from the center of the grid, as shown inFig. 2, and preferably connected together in a single integral piece bya series of vertical connecting-bars 17 to form a series of oblongreticulations or slots through the grid and through which the incomingsteam has free passage to impact against the vertical wall 13 for thepurpose and with the results above stated.

In the present construction the series of inclined bars 16 and theintermediate vertical connectingbars 17 will have a triangular shape incross-section, with their apices in the direction of the incoming steam,so as to offer a minimum obstruction to the same and in addition cause avery efficient division or dissemination thereof upon the impact-wall13.

In the preferred form of the grid or break 14, as shown more especiallyin Figs. 3 and 5 of the drawings, the same will have a concaveconvexform at each side of its vertical median line with a view to obtain amore effective division of the steam, 850., and in conjunction with thecentral upward extension or rib 13 of the impact-wall 13 effect auniform movement of the steam through the area of the separator in thepassage of such steam from the inlet to the outlet orifices.

19 is a drain-pipe adapted to convey the water, &c., caught in thechamber or compartment next adjacent to the outlet-orifice of theseparator down into the receiving-tank or holder of the separator.

In a more complex form of my present invention and one which is moreespecially adapted for use in vertically-extending or angularly-arrangedsteam pipes or mains, as illustrated in Figs. 4 and 5, a pair of theslotted or reticulated grids or breaks 14 will be employed in connectionwith a single vertical impact-wall l3 and the main separator-casing 1will be partitioned in the manner shown and provided withdirecting-openings 20 in such partitions adapted to guide the steam,

650., in a direct manner onto the grids or breaks in the manner and forthe purpose hereinbefore described.

No claim is made in the present application to the particulararrangement of chambers and inlet and outlet passages shown in Figs. atand 5, as the same is substantially involved in the subject-matter of acompanion application filed April 24, 1901, Serial No. 57,163.

The course of the steam through the apparatus is indicated by arrows inthe difierent figures of the drawings and will enter through theinlet-neck 4 and by means of the disseminating grid or grids 14 or 14 bedirected against the impact-wall 13 or 13, after which the steam passesin the circuitous manner indicated by the arrows toward the outletneck5.
